Background/PurposeCervical, thoracic, and pelvic neuroblastomas are regarded as having a better outcome than abdominal primaries. The aim of the study was to analyze the results of treatment of pelvic neuroblastomas in our institution.MethodsThe authors reviewed the records of 284 patients with neuroblastoma treated in our hospital during the period 1983 through 1998 and identified 17 (6%) with pelvic tumors. The revised International Neuroblastoma Staging System was used.ResultsThere were 6 patients with stage 1 disease, 8 with stage 2, 2 with stage 3, and 1 with stage 4 disease. Intraspinal extension of the tumor was present in 7 patients (41%). Except for one child with stage 4 disease, all patients underwent an attempt of tumor excision, and 6 had a complete resection. All 7 patients with intraspinal tumor survived. Permanent postoperative neurological complications occurred in 6 patients (35%). These included sciatic nerve palsy, urinary and fecal incontinence, neuropathic bladder, and leg weakness or nerve root injury L4-S1. Three of 17 patients died, but 1 fatality was unrelated to the tumor. The overall survival rate was 82% and was not influenced by the completeness of tumor resection.ConclusionsThe survival of nonmetastatic pelvic neuroblastoma in our institution is good despite incomplete tumor resection. Intraspinal extension is not a negative prognostic factor. Considering the high incidence of permanent neurological damage after surgery and the generally favorable biological characteristics of these tumors, surgical treatment should not be overaggressive.
